A substantial share of university instruction happens in tutorial sessions - small group instruction given parallel to lectures. In this paper, we study whether instructors with a higher academic rank teach tutorials more effectively in a setting where students are randomly assigned to tutorial...

In a previous paper, we have shown that academic rank is largely unrelated to tutorial teaching effectiveness. In this paper, we further explore the effectiveness of the lowest-ranked instructors: students. We confirm that students are almost as effective as senior instructors, and we produce...

The idea that students benefit from same-sex teachers has motivated policies around the world aimed at reducing gender inequalities. However, we do not know the size or generalizability of such same-sex teacher effects. We fill this gap by conducting a meta-analysis and our own study using data...

Hanushek et al. (2021) test how country-level measures of patience and risk-taking from the Global Preference Survey predict student performance on the Programme for International Student Assessment (PISA) math test. They find that country-level patience positively predicts math test scores and...

We study same-sex role model effects of teachers with a meta-analysis and our own study of three million students in 90 countries. Both approaches show that role model effects on performance are, on average, small: 0.030 SD in the meta-analysis and 0.015 SD in our multi-country study. Going...
